The public service broadcaster committed a "serious breach" of media regulations by not revealing that the presenter of a film about the Gaza conflict was the child of a Hamas administrator, as determined by British broadcasting authority Ofcom.
An investigation by Ofcom into the programme Gaza: How to Survive a Warzone has found that the film was "significantly deceptive".
The head of the BBC had earlier expressed regret, stating there had been "a significant failing in relation to factual correctness".
Ofcom has directed the corporation to broadcast a evening declaration about its findings.
"As this represents a serious breach of our regulations, we are ordering the BBC to transmit a message of our findings against it on the BBC's second channel at 9pm, with a timing to be confirmed," the statement read.
'Potential to Erode Credibility'
The regulator's report stated: "Our probe found that the programme's failure to disclose that the presenter's father occupied a role in the Hamas-controlled administration was significantly deceptive.
"This implied that the viewers did not have vital facts which may have been highly relevant to their assessment of the presenter and the content he shared.
"Credibility is at the center of the bond between a television network and its public, notably for a national broadcasting corporation such as the public broadcaster.
"This error had the risk to undermine the very considerable degrees of confidence that viewers would have invested in a factual film from the broadcaster about the Israel-Gaza war."
The film was removed from the online platform in the month of February after the presenter's familial connections were revealed, and in the month of July an internal BBC review found it breached the corporation's content policies on truthfulness.
A corporation official said: "The authority's determination is in agreement with the results of the internal assessment, that there was a significant failing in the programme in relation to the corporation's content standards on accuracy, which corresponds to Rule 2.2 of the regulator's media standards.
"We issued an apology for this and we comply with Ofcom's decision in full. We will follow the directive as soon as the timing and wording are finalised."
